Obesity is a major global health concern. This review explores ghrelin, a gastric hormone regulating appetite and body weight through the gut-brain axis.

Area of Science:

  • Endocrinology
  • Neuroscience
  • Physiology

Context:

  • Obesity is a significant global health issue linked to high morbidity and mortality.
  • Understanding the regulation of satiation, body weight, and energy expenditure is crucial.
  • The discovery of novel hormones in the gut-hypothalamic axis has advanced this understanding.

Purpose:

  • To review the physiological aspects of ghrelin.
  • To elucidate ghrelin's role in the regulation of satiation and body weight.
  • To highlight ghrelin's involvement in centrally mediated mechanisms.

Summary:

  • Ghrelin, a hormone primarily secreted by gastric tissue, plays a key role in regulating appetite and body weight.
  • It acts via centrally mediated mechanisms, involving neuropeptide Y and Agouti-associated proteins.

Related Experiment Videos

  • Ghrelin is a critical component of the gastrichypothalamic axis involved in energy homeostasis.

    • Impact:

    • Provides insights into the physiological functions of ghrelin.
    • Contributes to understanding the hormonal regulation of obesity.
    • Highlights potential targets for obesity management strategies.
